Django doesn't use atomic transactions by default?
I read the django documentation about Database transactions. Then, this section says: Django’s default behavior is to run in autocommit mode. Each query is immediately committed to the database, unless a transaction is active. So, as the section says, Django doesn't use atomic transactions by default? So, if Django doesn't use atomic transactions by default, when updating data in Django Admin Panel, there can be Race Condition right? -
How to solve refused to connect problem in Kibana?
I wrote a function for creating charts in Kibana. Firstly, I installed Kibana and Elasticsearch on my local PC. I am sending a request for creating data and charts and taking the embedded iframe code from there. In this scenario everything is okay. I could create charts clearly and my functions are working great. I could show charts on my page. Then I installed my project, kibana and elastic search on a server. And I get this error inside of the iframe tag: 2**...**6 refused to connect. What can be the problem? part of my functions elasticsearch_address= 'http://localhost:9200' self.es = Elasticsearch([elasticsearch_address], use_ssl=False, verify_certs=False, ssl_show_warn=False, send_get_body_as='POST', ) It works fine. I can get and post requests to this address.

Django - How to make a current object "ImageField attribute" as the pre-defined value in a Update_Object view?
I'm creating an update view using django-form for updating one of my objects that have the following fields: class Object(models.Model): name = models.CharField(max_length=40) logo = models.ImageField(upload_to='object_logo/') text_1 = models.TextField() text_2 = models.TextField() So, i have created the following form in forms.py: class ObjectForm(forms.ModelForm): class Meta: model = Object fields = [ 'name', 'logo', 'text_1', 'text_2', ] labels = { 'name': 'Name', 'logo': 'Logo', 'text_1': 'Text 1', 'text_2': 'Text 2', } and defined the following view called update_object: def update_object(request, value): object = get_object_or_404(Object, pk=value) if request.method == "POST": form = ObjectForm(request.POST, request.FILES) if form.is_valid(): object.name = form.cleaned_data['name'] object.logo = form.cleaned_data['logo'] object.text_1 = form.cleaned_data['text_1'] object.text_2 = form.cleaned_data['text_2'] object.save() return HttpResponseRedirect(reverse('myApp:detail_object', args=(value, ))) else: form = ObjectForm( initial={ 'name': object.name, 'logo': object.logo, 'text_1': object.text_1, 'text_2': object.text_2, } ) context = {'object': object, 'form': form} return render(request, 'myApp/update_object.html', context) My problem is: even with an "initial" value stetted up for logo, i have to select an image every time i will update my object (otherwise i receive the update_object page with the message "This field is required").

Revalidate on-demand a Next.js site from Django model's save method
I have a next.js site deployed to Vercel, that fetches data from an API provided by Django. Next.js has this new feature (Incremental Static Regeneration On-Demand) where you can rebuild a specific page without need to rebuild the entire site with an url like this: https://<my-site.com>/api/revalidate?secret=my-token I need the next.js site rebuild some pages when the database changes, so it shows the new data, and i tried to make a request (with requests package) in the save method like this: def save(self, *args, **kwargs): super(MyModel, self).save(*args, **kwargs) r = requests.get("https://<my-site.com>/api/revalidate?secret=<my-token>") It seems to work when it trigger that url from my browser, but it doesn't work when i trigger it from Django. The response of this Response object (r) is a 200 Status Code, as expected, with {"revalidated":true} (r.text), but it doesn't update the site anyways. How can i implement this? -

Does select_for_update() work if AUTOCOMMIT is set to False in Django Rest-Framework
I am writing a celery task which would get invoked if a row is being inserted into a table. This task is being executed in a transaction and the task also locks the certain rows of several tables. Now lets assume this task is being executed when AUTOCOMMIT & ATOMIC_REQUESTS is enabled. This is how it looks like - @app.task @transaction.atomic def celery_task(a, b): result = Orders.objects.filter(filed = "Value") # here the result might have 10 of records but I just need few of them based on a very # specific business logic. # so I pick those which are required and should be locked. rows_to_lock = [result[0], result[1]] # has only ids of the rows in this list # Now to put on the records which are in - rows_to_lock result = Orders.objects.select_for_update().filter(id__in=rows_to_lock) ... ... Now when this celery task is being invoked twice with two different arguments and at the same time and if the resultant rows of orders are exactly same then I have noticed that the locks to update the records aren't working. Does the decorator @transaction.atomic works with the current database configurations that I have? Will I be able to solve the issue if I … -
Django - How to go back to previous url
I have multiple todo lists on different pages in an app written in python. I dont want to use delete and update functions over and over again. I want to use one for all pages. In update and delete functions, I can redirect to a certain page after code execution. But its not dynamic. How can I make it dynamic? def updateTodo(request, pk): task = Todo.objects.get(id=pk) form = FormTodo(instance=task) if request.method == 'POST': form = FormTodo(request.POST, instance=task) if form.is_valid(): form.save() return redirect('/page_path') context = {'form':form} return render(request, 'update_task.html', context) What should I write instead of page_path so that it redirects to the page it comes from? I thought going back to the latest page would be an option but guess what? I couldnt do it either. Also, would going back create an error or something? since I'm updating an entry. Any suggestions ? (I saw some options with selenium but it seems to work for chrome or selected browsers only. I'd like to avoid using selenium if there is another way) -
